Definitions

  • the invention relates to a device for water purification with a container which can be filled with detergent, the jacket of which is provided with a flat lid and a flat bottom and which has a fixed curved partition wall to form an elongated bed for the detergent, delimited by sieves at the beginning and end.
  • a device of the type mentioned is known from US-A-2 037 332. Although there is already an enlarged bed height compared to the sleeve described above, the overall design can in no way be described as optimal. Apart from two partition walls arranged on concentric circles, empty spaces remain in the area in the area of the inlet and next to it in the area of the outlet, both of which extend from the cover to the bottom. This vomumen unused for water purification may not play a role in the known device because the housing is relatively large and is high. In the modern kitchens of households and restaurants, however, only a small amount of space is available today, so that the need for better use of space and the creation of a longer bed height has become more urgent.
  • the invention is therefore based on the object to improve a water purification device of the type described in US-A-2037332 in such a way that an even greater bed height is achieved without excessive space, so that such devices may also be used in the household, in restoration companies or in the industrial practice.
  • the partition is arranged spirally, the screens are fixed in the plane of the bottom and the lid and that the inlet is arranged in the middle of the lid and the outlet on the circumference of the bottom.
  • corresponding spiral lines are provided in the interior of the container, so that a long bed height for a filter mass is obtained in a narrow space when the filling mass is filled in for cleaning the water, preferably activated carbon, between the partition walls, namely in the resulting lines or ion exchangers or a mixture of these. Without the device becoming too unwieldy, the water to be cleaned can thus be kept in contact with the filling compound on a very long path from the inlet to the outlet.
  • the spiral shape is not only limited to the exactly geometrically ideal spiral, but the spiral can also be approximately oval, oblong or rectangular with rounded corners, whereby the container can be designed from round to square shape.
  • the device according to the invention permits effective cleaning, in particular demineralization, and it is also possible to use very fine filtration and, if necessary, separately or in combination to decarbonize the water.
  • the high quality of the filtered or demineralized water is obtained from the high height of the filter bed, a very long column is not required, which requires a lot of space and is difficult to accommodate. Rather, the device according to the invention is handy and practical to use and can be attached to a tap without requiring a large amount of space. You have a good cleaning quality, which is due to the arrangement of the sieves with respect to the height of the cylindrical casing and also the scope of which is favored, in particular by its combinatorial-functional interaction with the arrangement of the spiral partition.
  • the container of the cleaning device according to the invention can preferably be made of plastic, the outer jacket being essentially cylindrical. It differs in the embodiment described here from the exact cylinder shape, as seen in the section of the container, the spiral defines a helically widening channel that breaks off in its place, so that the outer walls here must have a transition in the radial direction .
  • this embodiment results in simple manufacture from the injection mold alone. This is used to inject a base or a cover with cast-on webs for the dividing walls, the container can then be filled with the filter material and then closed by attaching and fastening the cover.
  • Such a container can also be mass-produced inexpensively and reliably and reliably.
  • the thickness of the partition walls or the webs is preferably smaller than that of the cylindrical jacket and / or lid and bottom. Due to the large number of partitions arranged next to each other, the lid and base are at a fixed distance from one another, and the entire container is a compact and stable unit.
  • the inlet is provided in the form of a quick coupling with a pressure reducing nozzle.
  • the device according to the invention can be connected in a practical manner with a handle to a water tap provided with a corresponding coupling and is thus ready for use.
  • the pressure reducing nozzle ensures, during operation, that the water to be cleaned flows through a pressure drop from the network pressure to the operating pressure in the container filled with the filling compound, so that damage or even an explosion of the container is switched off even if it consists of plastic walls.
  • the usual water pressure in the supply network is a pressure of up to 6 bar.
  • the bed height naturally results from the length of the web or line filled with filter material through which the water to be cleaned has to be passed, that is from the water inlet to the outlet or in other words from one to the other.
  • pressure reducing nozzle Another advantage of the pressure reducing nozzle is the equalization of the pressure build-up when filling the water, i.e. when the device is started up, if after connecting and fastening the device with the help of the quick coupling, the tap is opened and the water pressure usual in the supply network is now present at the inlet.
  • the further advantage of reducing the water network pressure that the flow velocity is reduced and thus the contact time of the water with the filling increases.
  • the pressure reducing nozzle is mounted centrally at a distance above the upper sieve in the lid within the quick coupling, and the outlet at the outer end of the spiral is attached to the bottom in the form of a truncated cone-shaped tube in the region of the lower sieve.
  • a water jet for the emerging, purified water can thus be generated, so that this does not disadvantageously run along the outside, for example, and drips off at undesired places.
  • the outlet is preferably arranged at the outer end of the spiral
  • the inlet in the form of the quick coupling is located more in the central area.
  • the quick coupling forms the attachment of the device to the coupling on a tap, and the overall arrangement is better balanced, i.e. their weight is distributed more evenly at the tap when the quick coupling with reducing nozzle and upper sieve is in the center of the arrangement.
  • the space between the upper sieve and the pressure reducing nozzle creates a space within the housing of the quick coupling that allows good water distribution.
  • the upper strainer is firmly in the lid inside the quick coupling, i.e. is arranged in a mechanically strong, solid part, an approximately building up water pressure can advantageously be kept without breaking.
  • Such water pressure e.g. the pressure that is usual in the supply network can build up in the housing of the quick coupling in that dirt is supplied with the fresh water and settles in the quick coupling. Because of their firm design, the increased pressure building up behind the constipation point is then easily maintained and no leakage occurs.
  • the filter mass is safely held in the spiral container and is not pressed or flushed into the quick coupling.
  • a thickened support part in the form of a bead which is favorable in terms of flow technology is provided.
  • the arrangement of the support part only in the region of the center of the container can suffice.
  • the support member is preferably attached to the lid and bottom. It then connects these two walls and gives the entire container a very stable Shape.
  • such thickened support parts can also be attached off-center and / or at other locations. They are preferably always attached at the points of the highest mechanical stress.
  • the device according to the invention can be used in various areas, such as e.g. Household, catering and industry. While in the latter case the entire device is thrown away as a disposable item after the filter mass has been consumed, the spiral-shaped container, which has the shape of a flat cylinder, can be placed in a comfort device, e.g. a chromed filter device, which is attached to the tap, can be inserted.
  • a comfort device e.g. a chromed filter device, which is attached to the tap
  • the spiral or cylindrical container is merely an insert which, when the filling compound is exhausted, is replaced by a new one and discarded.
  • the state when the filling mass is exhausted is either indicated by a color indicator or e.g. checked by the taste of the water emerging at the outlet.
  • the cleaning device such as an insert or a cassette
  • a two-way valve is available, which optionally directs unfiltered water from the tap directly down into a basin for simple purposes, and on the other hand releases filtered water for higher demands in the other case after the changeover from the device.
  • the shape of the cassette can preferably also be rectangular, the interior of the aisle arrangement being more or less spiral, but in principle the flow path being spiral-like. i.e. the water to be cleaned flows from the inside out.
  • the water purification device has the generally designated 1 container made of plastic, which has an approximately cylindrical casing 2, a lid 3 and a bottom 4. Between the lid and the bottom there are spirally arranged partition walls 5.
  • the injection mold for the production of this container 1 is designed in such a way that the bottom 4 with the cylindrical jacket 2 and the web-like upstanding partitions 5 are formed with it.
  • the lower sieve 6 is either immediately molded on, or it is inserted and welded on afterwards.
  • a thickened support part 8 is provided in the region of the spiral center, which is preferably also molded onto the bottom 4.
  • the filling compound not shown, is then poured into the individual spiral channels, after which the cover 3 is placed on and e.g.
  • the upper sieve 7 is preferably molded onto the lid beforehand. Furthermore, a quick coupling 9 is formed on the lid 3 above the upper sieve 7. The inlet. Takes place via this quick coupling 9, which is molded or welded onto the cover 3.
  • the quick coupling 9 is, as shown in the figures, arranged centrally on the cover 3 and shown in FIG. 2 with a bead 10, over which a sleeve grips the tap in order to create a firm support connection between the stationary tap and the container 1 after coupling.
  • the quick coupling 9 has a pressure reducing nozzle 11 which is arranged at a distance above the upper sieve 7 in the quick coupling 9 in such a way that a space 12 results between the sieve 7 and the nozzle 11.
  • contaminants can accumulate which are prevented from entering the filling compound which is located in the spiral flow path. It can clearly be seen that each dividing wall 5 separates two paths arranged next to one another or represents the inside of one and at the same time the outside of the other flow path.
  • the outlet at the outer end of the spiral has the shape of a truncated cone-shaped tube 13 which is formed on the bottom 4 and receives the lower sieve 6 at the level of the bottom 4.
  • a flow rate of 60 l per hour is achieved in a practical exemplary embodiment, although a flow rate of 100 l of water per hour has already been achieved in another embodiment.
